MN is also one of only 2 states to allow “vouching” for people...and you can do so for (IIRC) up to 15 people.
IE: “see those 15 people behind me in line? they’re all my neighbors and I vouch for them being legit to vote”
How did they manage to elect a Republican House and Senate? Could it be that certain areas of the state have an overwhelming turnout of democrats on election day? Minneapolis, St Paul, Rochester, Deluth?
